Open BGL File
The files that have a BGL extension have various uses, some of them are listed below:
Babylon Glossary File
In this section, a BGL extension file is of type glossary text created by Babylon Glossary Builder, a program used to create Babylon glossaries.
Babylon
Babylon is a dictionary and, at the same time, a translation program developed by the Israeli company Babylon Software Ltd. based in the city of Or Yehuda, Israel.
Thus, the BGL format contains terms and their definitions in a proprietary text format, i.e. BGL only works with Babylon.
Flight Simulator File
In this case, the BGL file extension is a data file used by Microsoft Flight Simulator.
Microsoft Flight Simulator is a series of hobbyist flight simulation programs for the Microsoft Windows operating systems and earlier versions for MS-DOS and Classic Mac OS.
Thus, the BGL file contains scenario data, locations and routes.
It is noted that small scenarios require a single BGL file, while more complex locations and airports can use multiple BGL files.
Create and/or Modify a BGL file
Basically, the BGL files for Flight Simulator are Addons, and must be saved in specific directories, which each version of the software indicates.
It is important to note that the BGL files included in Flight Simulator must not be modified.
However, custom BGL files can be created to create custom airports and flight locations.
Custom BGL files can be created and compiled using third party programs.
